Our climate is so dry that we don’t see frost as much as I expected to. I regret that because I find it to be one of the most beautiful forms of precipitation.
This is one of my favorite frost pictures I have taken here because it tells something about the processes of nature. You can see the Yukon River in the background through the willows. It is difficult to tell, but the two leaves are nearly perpendicular to the river’s edge. The frost selectively grew from the leeward edge of the leaves directly away from the river. I believe it confirms that moisture forms over the Yukon, then flows onshore in measurable currents strong enough to influence crystal growth.
